As for high chairs- even though you wont be needing one for months- I dont regret spening money on mine. It has wheels and a bit between their legs to stop them from wiggling forward. To recline is an advantage too, and height adjustment.
I have friends who bought simple ones and dont regret it either.
I love my bouncer, it is one that they sit in, not curved like a capsule. Like a baby bjorn bouncer, but I didnt spend that sort of money (I bought both from Ebay).
I am now about to have our 3rd bub and still am happy to use these.
3 under 3- 15 month gaps. Busy but loving it eìí?
